Battery Repairs

Your car battery stores energy that it converts into electricity via a chemical reaction process. Your vehicle uses this energy when you run your starter motor, as well as for the ignition and fuel system. Breakdown services report having a flat car battery as the primary reason most vehicle owners call them out. When you find out you have a flat battery, it’s usually at the worst possible time. Sometimes you can jumpstart your battery but there are times when you will need to call your nearest breakdown service to come out and repair or replace it, in order to be able to start your car. The reasons for a dead car battery are varied, ranging from cold weather conditions to battery age, or too much excessive strain. You can also run your battery flat by taking too many short trips too often.

Can you fix a dead battery?

There are some things you can do yourself to try and revive a flat battery, though keep in mind sometimes the only thing you can do is replace a battery that just isn’t running anymore. First, you can try charging your battery, but if it’s totally run down, you probably won’t have much success. The next thing you should try is jump starting your car. You can do this with a jump starter pack, or with a set of jump leads and another car. However, make sure you know what you’re doing before you attempt a jump start, as otherwise you could injure yourself, or cause damage to your battery or your vehicle. Even if you succeed at jump starting your car battery, it’s longevity may have been shortened, so you’ll likely have to replace it at some point in the not so far off future. If you can’t charge your battery or jump start successfully, it’s probable your battery has a serious issue. You’ll need to call out a repair service to come and assess what’s wrong if you can’t get your car to the nearest garage. A mechanic will be able to tell you whether the problem is really caused by your battery, or if it is down to something else, like a faulty alternator. If the issue is with your battery, a mechanic will be able to replace and fit a new one. This shouldn’t take too long, although depending on how busy the garage is, your car may need to be in the shop for a day or so.

How long should I drive my car after a jump start?

Can you start your car? If so, let it run for a bit as having the engine going will charge up the battery. Remove the jump start cable clamps and drive for half an hour, then stop, and keep the engine running so the battery can continue charging. Don’t skip this step, as if you do, you may need to jump start all over again.

How much does it cost to fix a car battery?

Costs to replace a car battery vary, but in the UK, a replacement battery typically costs between £60 and £190, depending on if you have a conventional battery or one with stop/start technology. On top of this, you’ll have to pay the fitting and service cost which usually starts at around £35. Most of the costs for a battery replacement are from the parts as opposed to the work needed, so if you just need a minor repair or tweak, the fee should be significantly cheaper.

Can a car battery go dead from sitting?

It depends. Normally, most cars should be able to stay parked for around a month without the battery running flat, but if you have a luxury car with a lot of gadgets that guzzle power, your battery could go flat faster. You might be wondering why you can’t just park your car indefinitely and have the battery be as it was when you left it. This is because the chemical reaction your battery uses to convert energy into electricity keeps on happening, even when the engine’s not running. It just occurs more slowly, although you’re not using your vehicle. This why so many batteries run flat when they’re left in vehicles that are stationary for a long period of time.
